Be it known that I, Isaac WILLIAM PLEAS- ANT BUCHANAN, a resident ofLebanon, in the county of-Wilson and State of Tennessee-,have

invented certain new and useful Improvements in Lawn-Sprinklers; and Ido hereby .declare the following to be a full, clear, andexaetdeseription of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

Myinvention relates to an improvement in lawn-sprinklers, the object ofthe invention being to construct a lawn-sprinkler which shall beautomatic in operation and by means of which a considerable area can bewatered effectually and in acomparatively short-space of time.

A further object is to produce a sprinkler, which shall be simple inconstruction, by means of which a large quantity of water can be evenlydistributed over a correspondingly large area of ground, said sprinklerbeing so constructed as to be ornamental in appear ance and effectual inall respects in the per formance of its functions.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a structureembodying my invention. Figs. 2, 3, and i are views showing dilferentpositions which the parts assume during the operation of the apparatus.Fig. 5 is a view of a modification, and Fig. 6 is a detail view. I

A represents a frame, which may be made of metallic rods or tubing andmay also, if desired, be nickel-plated or otherwise ornamented. The baseportion of the frame or stand A comprises three legs 1 2 3, united attheir upper ends to the corners of a triangular frame 4. The leg 3 willpreferably be made in two sections normally sccured'together by means ofa suitable clamp 5, whereby said leg can be adjusted as to length so asto permit the apparatus to stand level when used on uneven-ground.

A triangular frame 6 is disposed below the frame 4 and secured at itscorners to the legs 1 2 3. The body portion of the stand comprises threeupright rods or bars 9 10 secured at their lower ends to the corners ofthe triangular frame 4 and having secured to their upper ends a ring B,of hard metal, such as steel, the rods or bars 9 being preferablycontinuations'of the legs 1 2. The bar or upright 10 may be madesomewhat larger'than the bars or uprights 9 and is made with a verticalslot 12 for the accommodation of the screw of aclamp 13. Thiselampcomprises 'a plate a, disposed against the bar or upright 10, apost I), projecting from said plate, clamping-arms 15, projecting fromsaid post and adapted to receive and hold a hose-pipe 14,

a screw c',passing through the slot 12 in the baror upright 10 andentering said plate, and a shoulder d on said screw to bear against theouter face of the bar or upright 10. The ring B is made in its upperedge with a groove g, in which an endless series of ratcl1etteeth h arelocated, the height of these teeth being somewhat less than the depth ofthe groove 9.-

Upon the ring B a movable device which for convenience I will term arotator is disposed. The rotator 0 comprises in its structure arectangular frame16, supported on said ring by means of arms 0 cl e f.The frame 16 is preferably of such size that its longest diameter willbe about one-half the diameter of the ring B, and at each end saidrectangular frame is provided with collars 18, having angular openings,and through said collars a transverse bar 19 is adapted to pass loosely.The transverse bar 1'9 is provided between its ends with a ring 20,through which-the hosefpipeis adapted to pass. Stops 21 21 are attachedto the arms 0 d and adapt ed to engage the inner face of the ring B,said stops being preferably made adjustable.

Stops 22 23 are adj ustably attached to the arms e f and are normallydisposed on said arms at points intermediate of the ring B and therectangular frame 16.- A'collart' is loosely mounted on each arm 0 d andprevented from lateral displacement by the walls of the groove g. Fromeach collar i a dog j projects and engages the ratchet-teeth h. I

The hose 14 is passed up through the ring 20 of the rotator, which is ofsuch diameter asito permit the hose to pass through it loosely, so as toavoid any binding between said hose and ring. The hose will be pulledhas made a portion of a revolution.

through the ring 20 untildhe nozzle at the end of said hose will beabout one foot (more or less) from the ring. The clamp 13 will be madeto grasp th'ehose. \Vhen the hose has been thus attached to theapparatus, the free ornozzle end thereof will hang loosely over the topof the stand or frame A. Should the water-supply be now turned on, thefrictional contact of the water against the curved free end of the hosewill cause it to rise. The force of the water which thus caused the freeend of the hose to rise will also cause it to move backwardly, thisbackward movement being permitted by the sliding transverse rod or bar19. of its movement, the ring in the center thereof will strike the endof the rectangularframe -16, and by the jar th-us caused the free end ofthe hose will be thrown over, as indicated by dotted lines in Fig. 1.The jar caused by the engagement of the ring 20 with the end of therectangular frame will also cause saidframe to move on one of the stopsor pins 21 as a pivot until the adjustable stop 22 or 23 engages thering B. By this time the free end of the hose will have completed itsoscillatory movement in the arc of a circle and will be thrown back bytheaction of the force of the water in the same manner as aboveexplained, but now a new portion of the ground will be watered, as therectangular frame 16 This action of the apparatus will continue, thenozzle end of the hose oscillating back and forth in the arc of a circleand the rectangular frame making a slight movement at each oscillationof the end of the hose, until the frame 16 has made a completerevolution and a circular path of ground has been watered.

By providing the ratchet device above'described all lost motion when therotator turns on the pivot pins orjstops will be prevented.

Without the ratchetdevice little irregularities of trend or flexibilityof the hose-pipe would tend to interfere with perfect rotation oftherotator, but with said ratchet devices the operation of the rotatorwill be uniform regardless of the irregularities above mentioned. I I

I have demonstrated byactual experiment that by means of my improvedapparatus-I am enabled to thoroughly water a very large area of groundin a comparatively short space of time.

It will be observed that the movements of the hose are above the clamp13, and thisclamp'ismade adjustable, as above explained, to accommodatethe apparatus to hose-pipes of different degrees of flexibility anddifferent pressures of water. In order to insure the accurate operationof the devices above described, at the upper end of the stand theapparatus should be level, and for this purpose one of the legs is madeadjustable, as above described.

When it is desired to water a rectangular piece of ground, the stops 2223 will be move When the bar 19 reaches the 'end'.

out on the arms ef until they engage the ring 13, so as to prevent therotation of the rectangular frame ll).

The hose-pipe used may be flexible throughout or it may be made offlexible and rigid sections, if desired.

Where the-pressu re is more severe than ordinary the free or nozzle endof the hosepipe might vibrate so rapidly as to cause un" necessaryfriction, the full throw of the hose: pipe would not be utilized and thediameter of the watered area would be shortened. To insure the propervibration of the nozzle end of the hose-pipe under varying, pressures ofwater, I prefer to i'u'ljustably attach a weight 26 to said hose-pipebetween the rotator (3 and the nozzle.

Instead of the transverse sliding bar 10, above described, therecta'ngularframe 16 may be made withan elongated slot 27, in which thehose can move back and forth, as shown in Fig. 5

My improvements are simple in construe: tion, comprise few parts, areornamental in appearance, will operate to distribute water thoroughlyover a large area, and are eifcctu'al in all respects in the performanceof their functions.

.Various slight changes might be made in the details'of construction ofmy invention without departing from the spirit thereof or limiting itsscope, and hence I do not-wish to limit myself to the precise details ofconstrue Patent, is-
